Abstract
Abstract. In this paper, defeasible workflow is proposed as a framework to support exception handling for work-flow management. By using the “justified ” ECA rules to capture more contexts in workflow modeling, defeasible workflow uses context dependent reasoning to enhance the exception handling capability of workflow management systems. In particular, this limits possible alternative exception handler candidates in dealing with exceptional situations. Furthermore, a case-based reasoning (CBR) mechanism with integrated human involvement is used to improve the exception handling capabilities. This involves collecting cases to capture experiences in handling ex-ceptions, retrieving similar prior exception handling cases, and reusing the exception handling experiences captured in those cases in new situations.
